"The improvement can be such that we can make cars that drive safer than people do," Anthony Levandowski, product manager for Google's self-driving car technology, told a Society of Automotive Engineers meeting in Washington last week. "I can't tell you you'll be able to have a Google car in your garage next year. We expect to release the technology in the next five years. In what form it gets released is still to be determined."

As Gizmodo reported last year, California Gov. Jerry Brown signed a bill into law effectively legalizing driverless cars in that state. Google co-founder Sergey Brin said at the time that he hopes the technology will one day aid people who can't drive on their own, as well as improve traffic safety.

Just moments ago, California Governor Jerry Brown signed into effect SB1298, effectively paving the …

So are we well on our way to ceding control of our cars to computers? Well, maybe not yet. As the Bloomberg story notes, there's a lot more to this than just the technology behind the cars themselves. There are also laws, regulations, safety standards and insurance policies that may have to be radically modified to allow this kind of thing. Still, at least some of them seem to be for it — David Strickland, head of the U.S. National Highway Traffic Safety Administration, said he's interested in such a system's potential for reducing crashes.

Google says they aren't interested in commercializing driverless cars, just developing that technology itself. And there are still a lot of challenges involved there: if the system fails, nothing will be driving the car, Levandowski told Bloomberg. Also, who's at fault if there's a crash?

We already have systems on higher-end luxury cars that warn drivers of impending hazards, and Mercedes-Benz is even putting its autonomous steering assist on the new S-Class. Driverless cars are coming — but we'll just have to wait and see what shape they take in the coming years.
